I have the Preludes as well in a dual purpose set up with an Anthem D1, PS Audio HCA2 for the fronts and just recently switched from Audioquest Pikes Peak to MIT MH750 Plus S2s and the difference was remarkable. I have AQ Jaguar balanced interconnects and looking for a way to mellow out the highs just a tad. My room is awful, and there isn't anything I can do at the present time about that. Any suggetions would be useful.
